FLUSH TANK DISINFECTANT DISPENSER Filed April 5, 195o A 2 sneets-sht 2 ATTO RN EYS Patented Aug. 4, 1953 UNITED STATES PATENT OFFICE FLUSH TANK DISINFECTANT DISPENSER Antone Nunes Viena, Honolulu, Territory of Hawaii Application April 5, 1950, Serial No. 154,100

invention relates to a trap having a valve and "a vent therein adapted to be threaded on a depending neck of an inverted container with the container positioned in a. iiush tank below the normal water level therein. V

The purpose of this invention is to provide a disinfectant device in which Adispensing means thereof is operated by the rise and fall oi water in a, tank in which the device is positioned in which the amount of' disinfectant dispensed is controlled from the upper end ofl the tank without inserting the hand in the water therein.

This application is a continuation in part ci' my co-pending application filed August 24, 1948 with the Serial Number 45,851, now matured into Patent No. 2,61i265,l dated Qctober 21, 1952, the dispensing unit of this, invention including suhstantially a comparatively small cap threaded on the neck of a bottle with a valve provided in the cap and with a vent extended from one side thereof.

Various attempts have been made to provide disinfecting devices for toilet bowl, iiush tanks and the like but where these devices operate con.- tinuously the quantity of the disinfectant used is excessive and as dsinfectants for this purpose are comparatively costly these devices are very seldom used. With this thought. in mind thS invention contemplates a disinfectant dispensing cap that may be threaded on the .nook of a bottle A oidisinfectant and. which, when inserted in a ilush tank of a toilet bowl dispenses d isinfeci--` ant .only with the rise. and fall of water in the tank.

The object of this invention is, therefore, to provide means for forming a cap that, may be threaded on the neck of a bottle. of disinfectant whereby disinfectant may be dispensed from the bottle with the bottle in an. inverted position by the rise and fall of water in a tank. in which the bottle is positioned.

Another object of the invention is to provide 3 Claims. (Cl. iw-2.27)

A furtherobiect of the invention is to provide a disinfectant dispensing device for toilet bowls that is operated by changes in elevation of water in the tank and that may be adjusted from a point above the water level in the tank and which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies an internally threaded cap havinga vent extended outwardly and upwardly from one side thereof with a boss on the closed end of the cap and with a valve extended from the boss and having a stem eX- tended upwardly .through guide means in which the bottle or container is positioned.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a side elevational view illustrating a bottle or container in a supporting bracket in the iush tank of a toilet bowl with the tank and dispensing cap threaded on the lower end of the bottle shown in section.

Figure 2 is a cross sectional downward view through the holder for the bottle taken on line 2-2 of Figure 1.

Figure 3 is a view looking upwardly toward the under surface of the lower end of the dispensing device.

Figure 4 is a side elevational view showing the lower end of the dispensing device illustrating a modication wherein the valve stem is slidably actuated.

Figure 5 is a similar view illustrating a valve of a different type threaded in the plug of the dispensing cap.

Figure 6 is a similar view showing a further modicaton wherein a different type of valve is used in the dispensing cap. v Figure 'Z is a view illustrating a further modi* cation wherein a niling nipple and cap are provided on the upper end of lthe bottle and container and in. which the said filling nipple and cap are shown in sections.

Referring now to the drawingsv (Figures l, 2 and 3) wherein like reference characters denote corresponding parts the flush tank disinfectant dispenser of this invention includes a cap I0 having a boss Il on the lower end with a vent tube IZ- extended from one side of the cap, and a valve t3 threaded in the lowerend of the boss, and with a valve stem It extended upwardly through a tubularguide l5 of a holder I'l for a bottle or container ll'.

The cap l0 is internally threaded and, as illustra-ted in Figure l, the cap is threaded on a neck f8 ofthe bottle Il with a gasket I9 between the' end of the cap and surface of the bottle.

The vent tube l2 is integrally mounted in an opening in one side of the cap and the upper end extends upwardly to a point 2i which is a suicient distance above the lower end of the cap to prevent water flowing therefrom.

The valve I3 is provided with a sleeve 22, the end of which is threaded into an opening 23 in the lower part of the boss i i, the center of which is provided with an opening 24 that provides communicating means between the interior of the cap and an opening through the sleeve 22.

The upper end of the valve i3 is threaded to receive the lower threaded end 25 of the valve stem i5 and the upper end of the valve stem is provided with a knob 26 by which the valve stem may be turned to regulate the size of the opening from the sleeve 22 through the valve.-

The holder i6 is provided with a bracket 2ll that extends over the upper edge of an outer wall 28 of a flush tank, the upper end of which is provided with a cover 29.

In the design illustrated in Figure 5 a cap 3 is positioned on a neck of a bottle or container 3l with a packing washer 32 between-the upper end of the cap and wall of the container and the cap, which cap is provided with a vent 33 similar to the vent l2, and boss Sli having an opening 35 extended therethrough, the area of the opening being controlled by a screw 36 having a head 3l, which is threaded into an opening 38 in the boss and which is positioned so that the inner end thereof extends into a recess 39 on the opposite side of the opening 35.I By this means the area of the opening 35 is controlled by the screw 36 and the screw is set by hand, either before the dispenser is installed in the flush tank or after it is in position therein.

The design illustrated in Figure 4 is substantially the same as that shown in Figure l except that the threads on the lower end of the stem 4i?, similarto the stem lll are omitted and the i opening 4I in the sleeve s2, similar to the sleeve 22 is controlled by sliding the stern di! upwardly or downwardly in an opening 43 in the valve 44. The sleeve 42 extends from one side of the boss 45 depending from a cap 4G and the cap is provided with a vent 4l, the parts being substantially the same as corresponding parts of the dispenser shown in Figure 1.'v The cap 48 is threaded on a neck of a bottle or container 48 and the container is positioned in a holder 49.

In the design shown in Figure 6 a cap 5l?, similar to the cap lll is provided with a nipplev 5l having a Valve 52 rotatably mounted therein and the valve is provided with a passage 53, the position of which is controlled by a handle 54 on the outer end of a stem 55. The valve 52 is also provided with a stem 56 having a spring 5l positioned between a washer 58 on the outer end thereof and the end of the valve cylinder 55. A nut 5t is provided on the outer end of the stem 56 and the cap 5B is provided with a vent In the design illustrated in Figure '7 a con-- tainer E2 is provided with a cap 63 which may be similar to the cap l0 or formed like the caps 30, 46 or 5i! and this cap may be threaded orl otherwise secured to a neck 54 0n the lower endl.` of the bottle or container. The container 62 is also provided with a iilling nipple having a closure cap 66 thereon and a sealing washer or gasket 61 may be provided in the cap.

It will be understood that the filling nipple may be used with the bottle or container of the other design and caps of any suitable type or de.- sign may be used on the lower end thereof.

the other design.

As disinfectant is used from the container the cap is removed and placed on another container or the same container may be filled and reused.

It will be understood that other modifications `may be made in the design and arrangement of the `partswithout departing from the spirit of the invention.
